Detailed Descriptions for the elements in the MedicationAdministration resource.

MedicationAdministration
Element IdMedicationAdministration
Definition

Describes the event of a patient consuming or otherwise being administered a medication. This may be as simple as swallowing a tablet or it may be a long running infusion. Related resources tie this event to the authorizing prescription, and the specific encounter between patient and health care practitioner.

Element IdMedicationAdministration.dosage.text
Definition

Free text dosage can be used for cases where the dosage administered is too complex to code. When coded dosage is present, the free text dosage may still be present for display to humans.

The dosage instructions should reflect the dosage of the medication that was administered.

Comments

If the use case requires attributes from the BodySite resource (e.g. to identify and track separately) then use the standard extension http://hl7.org/fhir/StructureDefinition/bodySite. May be a summary code, or a reference to a very precise definition of the location, or both.

MedicationAdministration.dosage.route
Element IdMedicationAdministration.dosage.route
Definition

A code specifying the route or physiological path of administration of a therapeutic agent into or onto the patient. For example, topical, intravenous, etc.

Short DisplayPath of substance into body

TypeCodeableConcept
Summaryfalse
MedicationAdministration.dosage.method
Element IdMedicationAdministration.dosage.method
Definition

A coded value indicating the method by which the medication is intended to be or was introduced into or on the body. This attribute will most often NOT be populated. It is most commonly used for injections. For example, Slow Push, Deep IV.

Short DisplayHow drug was administered
Cardinality0..1
Terminology BindingSNOMED CT Administration Method Codes (Example)
TypeCodeableConcept
Summaryfalse
Comments

One of the reasons this attribute is not used often, is that the method is often pre-coordinated with the route and/or form of administration. This means the codes used in route or form may pre-coordinate the method in the route code or the form code. The implementation decision about what coding system to use for route or form code will determine how frequently the method code will be populated e.g. if route or form code pre-coordinate method code, then this attribute will not be populated often; if there is no pre-coordination then method code may be used frequently.

MedicationAdministration.dosage.dose
Element IdMedicationAdministration.dosage.dose
Definition

The amount of the medication given at one administration event. Use this value when the administration is essentially an instantaneous event such as a swallowing a tablet or giving an injection.

Short DisplayAmount of medication per dose
Cardinality0..1

Comments

If the administration is not instantaneous (rate is present), this can be specified to convey the total amount administered over period of time of a single administration.

MedicationAdministration.dosage.rate[x]
Element IdMedicationAdministration.dosage.rate[x]
Definition

Identifies the speed with which the medication was or will be introduced into the patient. Typically, the rate for an infusion e.g. 100 ml per 1 hour or 100 ml/hr. May also be expressed as a rate per unit of time, e.g. 500 ml per 2 hours. Other examples: 200 mcg/min or 200 mcg/1 minute; 1 liter/8 hours.

Short DisplayDose quantity per unit of time
Cardinality0..1
TypeRatio|SimpleQuantity
[x] NoteSee Choice of Datatypes for further information about how to use [x]
Summaryfalse
Comments

If the rate changes over time, and you want to capture this in MedicationAdministration, then each change should be captured as a distinct MedicationAdministration, with a specific MedicationAdministration.dosage.rate, and the date time when the rate change occurred. Typically, the MedicationAdministration.dosage.rate element is not used to convey an average rate.

TypeReference(Provenance)

Comments

This might not include provenances for all versions of the request – only those deemed “relevant” or important. This SHALL NOT include the Provenance associated with this current version of the resource. (If that provenance is deemed to be a “relevant” change, it will need to be added as part of a later update. Until then, it can be queried directly as the Provenance that points to this version using _revinclude All Provenances should have some historical version of this Request as their subject.
